From time to time you might see a post in Tech Talk containing little other than the word “bump”. These posts are made to bring the thread to the attention of people that may otherwise have missed it. If a question is asked when no-one who knows the answer is online then many other threads are started, the question may be buried far back in the thread-history by the time someone who can answer it arrives, so they may miss it completely. A little “bump” post brings the thread to the top of the “View By Time” list so that whoever is around will notice it.
There is an extremely long thread dedicated to the joys of “bump” starting here.1) Go on, bump it, you know you want to.
